In the Agricultural Act of 2014 (“2014 Farm Bill”), Congress exempted “industrial hemp” from the Controlled Substances Act (“CSA”) in certain narrow circumstances. Among other things it authorized institutions of higher education and state agriculture departments to grow hemp under a pilot program if consistent with state law, and defined hemp to include up to 0.3 percent of the psychoactive cannabinoid tetrahydrocannabinol (“THC”) on a dry weight basis. The Agriculture Improvement Act of 2018 (“2018 Farm Bill”) expanded under certain circumstances the legality of hemp, legalizing its production as an agricultural commodity, and removing it from the list of controlled substances along with all derivatives, extracts, and cannabinoids among other compounds with a similarly low amount of THC.
